Music is an art, entertainment, or other human activity that involves organized and audible sounds and silence. It is expressed in terms of pitch, rhythm, harmony, and timbre. Music involves complex generative forms in time through the construction of patterns and combinations of natural stimuli, principally sound. As a human activity, music may be used for artistic or aesthetic, communicative, entertainment, or ceremonial purposes. The definition of what constitutes music varies according to culture and social context.

The broadest definition of music is organized sound. There are observable patterns to what is broadly labeled music, and while there are understandable cultural variations, the properties of music are the properties of sound as perceived and processed by humans.A more conservative definition would be: Music is harmonious sound created by the playing of instruments as a whole or individually. It is a direct expression of human emotions designed to manipulate and transform the emotion of the listener/listeners. Music is designed to be felt unlike sound which is heard.

In geography, temperate latitudes of the globe lie between the tropics and the polar circles. The changes in these regions between summer and winter are generally subtle, warm or cool, rather than extreme, burning hot or freezing cold. However, a temperate climate can have very unpredictable weather. One day it may be sunny, the next it may be raining, and after that it may be cloudy. These erratic weather patterns occur in summer as well as winter.
The north temperate zone extends from the Tropic of Cancer at about 23.5 degrees north latitude to the Arctic Circle at about 66.5 degrees north latitude. The south temperate zone extends from the Tropic of Capricorn at about 23.5 degrees south latitude to the Antarctic Circle at about 66.5 degrees south latitude.
Within these borders there are many individual climate types, which are generally grouped into two categories: continental and maritime.
The maritime climate is clearly affected by the oceans, which help to sustain somewhat stable temperatures throughout the year. In the temperate zones, the prevailing winds are to the west, the western edge of temperate continents most commonly experience this maritime climate. Such regions include Western Europe, especially the UK, and western North America at latitudes between 40° and 60° north.
The continental climate is usually situated inland, with warmer summers and colder winters. The large land mass increases its effects on heat reception and loss. In North America, the Rocky Mountains act as a climate barrier to the maritime air blowing from the west, creating a continental climate to the east. In Europe, the maritime climate is able to stabilize temperatures further inland, because the major mountain range - the Alps - is oriented east-west.
The idea of a temperate "zone" was first hypothesized by the ancient Greek scholar Aristotle. He said that the earth was divided into three types of climatic zones, based on their distance from the equator.
Thinking that the area near the equator was too hot for habitation, Aristotle dubbed the region around the equator as the "Torrid Zone." He reasoned that from the Arctic Circle to the pole was permanently frozen. He called this uninhabitable zone the "Frigid Zone." The only area that Aristotle believed was livable was the "Temperate Zone", lying between the "Frigid Zone" and the "Torrid Zone". One of the reasons Aristotle believed that the Temperate Zone was the best for life could come from the fact that he lived in that zone.
As knowledge of the earth's geography improved a second "Frigid Zone" was discovered south of the equator around the Antarctic and a second "Temperate Zone" was discovered south of the equator.
